GATE-ACTUATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 349,869, datedSeptember 28, 1886.

Application filed April 24, 1885.

To all whom, it may concern.-

Be it known that I, WILLIAM RICHARD IVHITE, a citizen of the UnitedStates, and a resident of Neoga, in the county of Cumberland and Stateof Illinois, have invented certain new and useful Improvements in Gate-Actuating Mechanism, of which the following is a specification.

My invention relates to that class of gates in which avertically-reciprocating bar is the means of communicating motion fromthe operating-lever to the gate; and the invention consists in theconstructions and combinations of parts, substantially as hereinafterset forth.

In the drawings, Figure 1 is a side elevation of a sliding gateillustrating my improvement.

2 is an end elevation.

For the purpose of illustrating my invention I have shown it inconnection with agate having an extended upper rail, a, sliding uponguide-wheels b b, turning upon pins projecting from standards A B, andsupporting the gatepanel D, which slides back and forth across theroadway to and from the post E. The standard A is provided with acrosspicce. O, to which are pivoted the operating-levers F I Theoperating-levers are connected at their inner ends to thevertical]y-reciprocating bar G, the connection, as shown, consisting ofa pin, 0, extending from the bar through slots in the ends of thelevers; but any other suitable connection may be employed whereby theswinging of the levers upon their pivots is made the meansofreciprocating the bar, and the said bar is connected at the lower endto a connecting-rod, f, pivoted at its lower end to the gate-panel, sothat the downward pull of the outer end of either lever F will be themeans of swinging the gate back and forward, as set forth in the LettersPatent granted to me May 23, 1882, No. 258,517. In the class of gatesillustrated in said patent the bar G slides in guides supported by thestandard A, and these are apt to become rusty, and when oiled to becomeclogged and gummed with oil and dirt, so as to create considerablefriction and interfere with the movements of the gate. Anotherdisadvantage arising from the use of the guides is the rapid wear bothof the guides and the reciprocating rod. In order to overcome thesedisadvantages, I connect the rod G pivotally to the ends of two or moreparallel arms, h 71-, pivoted at their rear ends to a suitablesupport-as, for instanee,thestandard B which arms rise and fall with thebar G as SerlalNo.163,313. No model.)

it is operated by thelevers F, but without any other friction than thevery limited friction arising from the swinging of the arms h upon theirpivots. The arrangement above described not only avoids the frictionresulting from the use of guides, but also prevents the increase offriction resulting when oil or other lubricant is employed when theroads are dusty, while the whole arrangement is much more durable thanthe rods sliding in guides, as heretofore. The arms It may be pivoted toany suitable stationary part of the gate, and may be arranged behind thebar G, as shown, or at either side of the same parallel to the roadway,and in order to prevent them from swinging laterally they may beextended between the side of the standard and a strip, 8, fixed at ashort distance from the same, as shown, which strip does not interferewith their vertical movement, but prevents them from sagging laterally.

\Vhile I have illustrated the bar G in connection with a sliding gateand rod, f, I have done so for the purpose of illustration only, as theguiding-links or rod-arms It may housed in connection withvertically-moving rods arranged to operate gates of different charactersthrough the medium of j ointed arms or crankarms, or any of the usualoperating appliances. The bar G may also be used in connection with asingle operatingarm, F, arranged in any suitable manner.

Without limiting myself to the precise construction and arrangement ofparts shown and described, I claim 1. In a gate, the combination,withthe vertical standards A B, each carrying rollers upon which the gateslides, of a reciprocating bar, G, connected by a pitman to the gate,and a pair of parallel arms, 71, pivoted at one end to the standard Band at the other to the bar G, substantially as described and shown.

2. The combination, with the vertical standards A B, the sliding gate,the reciprocating bar G, and the pitman f, of the parallel links it hand the strip 8, substantially as described and shown.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.
